Thanks all.
I’m planning on having a good trawl around the Beaulieu Jumble next Sunday to see what I can find, but thought I’d ask on here first.
Nos knows what I’m up to, but it needs to surprise somebody so I can’t say too much.
I got hold of a boat/caravan domestic water pump a couple of months ago, but unfortunately it just didn’t have enough grunt, and a windscreen washer pump won’t shift enough water.
The Nomad 12V pressure washer is a great piece of kit, which I’d already found, but we’re in the £25 bracket, so it’s way out of our league to use as a power source.
Nos, the 25l containers look good, I’ll probably pick one up for camping anyway.
The sort of kit we need does exist, Shurflo is just one make:
ProBlaster™ Washdown Pump - SHURflo
but they are just too expensive, so I’m looking for a second-hand one.
Nasher.
